Hi re lunasin. I am not sure. I have not tried it due to expense and already taking as much as I can tolerate in the way of supplements. I have been following the stories of our members though and if the positive stories continue it might be worth a try if you can afford it. For me, there is the added issue that I am FALS. The cause is known and presumably different from those who are showing benefit. What helps SALS may not help me
